CMAKE_PROJECT_COMPAT_VERSIONΒΆ
Added in version 4.3.
The compatibility version of the top level project.
This variable holds the compatibility version of the project as specified in
the top level CMakeLists.txt file by a project() command. In the
event that the top level CMakeLists.txt contains multiple project()
calls, the most recently called one from that top level CMakeLists.txt will
determine the value that CMAKE_PROJECT_COMPAT_VERSION contains. For
example, consider the following top level CMakeLists.txt:
cmake_minimum_required(VERSION 4.3)
project(First VERSION 9.0 COMPAT_VERSION 1.2.3)
project(Second VERSION 9.0 COMPAT_VERSION 3.4.5)
add_subdirectory(sub)
project(Third VERSION 9.0 COMPAT_VERSION 6.7.8)
And sub/CMakeLists.txt with the following contents:
project(SubProj VERSION 2.0 COMPAT_VERSION 1.0)
message("CMAKE_PROJECT_COMPAT_VERSION = ${CMAKE_PROJECT_COMPAT_VERSION}")
The most recently seen project() command from the top level
CMakeLists.txt would be project(Second ...), so this will print:
CMAKE_PROJECT_COMPAT_VERSION = 3.4.5
To obtain the version from the most recent call to project()
in the current directory scope or above, see the
PROJECT_COMPAT_VERSION variable.
